Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Messaging

The latest iteration of the flagship Fenix adventure watch introduces a potentially lifesaving feature: phone-free messaging and SOS alerts using 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, plus an available state-of-the-art microLED display in a special edition. This is Garmin's top model and engineered to be the only tool needed to explore almost any location and monitor all your movements.

That makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading workout, activity and outdoor monitoring. The full offline mapping of the world can seamlessly guide you back to the trail if you lose your way without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life even with the display always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your mobile carrier, as with other wearables. But unlike competing satellite-capable devices, emergency communication is not provided for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and audio messages, calls and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable pursuits – plus emergency satellite SOS messaging.

Location updates and messages over satellite are then charged on top, with more expensive plans offering different allowances of orbital use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via text or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable canned replies you can use to speed things up. Spoken messages and calls work acceptably, though as with most wearables, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to chosen contacts every time you start an activity, so they can track your real time location on a map. It’s excellent for following race progress, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked well, although the actual position has sometimes lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is essential to remember that orbital service is limited to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services offered via the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal schemes on recent purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re without signal.

The result is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. At least it is not reliant on your phone provider so functions with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but still wants to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks everything with premier GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and orbital features need monthly subscription, limited Garmin Pay financial compatibility, voice features are sluggish, basic smartwatch functionality versus competing watches.
